Detailed Implementation

[0016] The present invention will now be described in conjunction with specific embodiments.

[0017] Example 1, as Figure 1 and Figure 2 As shown, a novel dispensing-assisted centering fixture includes a fixture support, on which a substrate 1 is arranged horizontally.

[0018] In this embodiment, a horizontally arranged movable turntable 2 is rotatably mounted on the upper side of the substrate 1, and a magnetic strip (not shown in the figure) is installed on the upper surface of the movable turntable 2; a drive motor 3 is installed on the substrate 1 corresponding to the movable turntable 2, and the drive motor 3 is drivenly connected to the movable turntable 2. It should be noted that the drive motor 3 in this embodiment can be a geared motor.

[0019] Furthermore, a jig centering block 4 is screwed onto the upper surface of the substrate 1 next to the movable turntable 2. The upper end of the jig centering block 4 is provided with a jig centering groove 41 that contacts the locking jig 100 during use and is in the shape of an arc.

[0020] Furthermore, the upper end of the fixture centering block 4 is equipped with a workpiece centering block 5. The workpiece centering block 5 is provided with a workpiece centering groove 51 that contacts the workpiece 101 during use and is in the shape of an arc. The fixture centering groove 41, the workpiece centering groove 51, and the movable turntable 2 are arranged coaxially.

[0021] The following describes in detail the novel dispensing-assisted centering fixture of Embodiment 1, with reference to its specific usage process. The usage process includes the following steps: Step a: Place the locking fixture 100 on the upper surface of the movable turntable 2, and place the workpiece 101 on the upper surface of the locking fixture 100. The movable turntable 2 magnetically attracts the locking fixture 100 through the magnetic strip, so that the locking fixture 100 is kept on the upper surface of the movable turntable 2. The locking fixture 100, after being magnetized by the magnetic strip, also has a certain magnetic attraction force on the workpiece 101. Step b: Start the drive motor 3. The drive motor 3 drives the movable turntable 2 to rotate slowly. During this process, the locking fixture 100 and the workpiece 101 rotate synchronously with the movable turntable 2. The operator abuts against the locking fixture 100 towards the fixture centering groove 41 and against the workpiece 101 towards the workpiece centering groove 51, so that the locking fixture 100 contacts and adheres to the surface of the fixture centering groove 41 and the workpiece 101 contacts and adheres to the surface of the workpiece centering groove 51, so as to complete the centering action of the locking fixture 100 and the workpiece 101. Since the fixture centering groove 41, the workpiece centering groove 51 and the movable turntable 2 are arranged coaxially, the locking fixture 100 and the workpiece 101 can be aligned and centered. Step c: The operator holds and operates the automatic glue sprayer. As the centered locking fixture 100 and workpiece 101 rotate synchronously, the automatic glue sprayer sequentially completes the glue application operation at the joint between the locking fixture 100 and workpiece 101.

[0022] It should be emphasized that the novel dispensing-assisted centering fixture in this embodiment can achieve rapid and accurate centering of the locking fixture 100 and the workpiece 101. After the locking fixture and the workpiece 101 are centered, the movable turntable 2 driven by the drive motor 3 drives the locking fixture 100 and the workpiece 101 to rotate synchronously. The dispensing between the locking fixture 100 and the workpiece 101 can then be completed by the automatic glue spraying machine. The dispensing operation is fast and convenient.

[0023] In summary, the novel dispensing-assisted centering fixture of this embodiment has the advantages of novel design and simple structure, and can effectively improve dispensing speed through the above structural design. Example 2, as Figure 1 and Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is that the workpiece centering block 5 is located in the fixture centering groove 41 of the fixture centering block 4, and the workpiece centering block 5 is provided with an arc surface 52 that fits into the fixture positioning groove.

[0024] Among them, the centering block 4 of the fixture is fitted with an auxiliary stop block 62 by a locking screw 61.

[0025] Specifically, when the rotating workpiece 101 comes into contact with and adheres to the surface of the workpiece centering groove 51, the workpiece 101 will rub against the workpiece centering block 5. At this time, the auxiliary stop block 62 blocks the workpiece centering block 5 to prevent the workpiece centering block 5 from retracting from the fixture centering groove 41. Example 3, as Figure 1 and Figure 2 As shown, the difference between this embodiment 3 and embodiment 1 is that: the drive motor 3 is screwed onto the lower surface of the substrate 1, the upper surface of the substrate 1 is provided with a bearing seat 71, the bearing seat 71 is rotatably mounted with a vertically arranged drive shaft 8 through a bearing 72, the power output shaft of the drive motor 3 is connected to the lower end of the drive shaft 8, and the upper end of the drive shaft 8 is screwed onto the movable turntable 2. Example 4 differs from Example 1 in that: the upper surface of the movable turntable 2 has a turntable mounting hole (not shown in the figure) corresponding to the magnetic strip, and the magnetic strip is embedded and fixed in the turntable mounting hole.

[0026] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
